Solution of the electrodiffusion equations, together with the Poisson equation, was examined. It was demonstrated that, in the main small-parameter approximation, the problem was reduced to the solution of 2 first-order differential equations. The equations obtained permitted transition processes in systems of charged particles to be treated for an arbitrary time dependence of the external potential.
